Next New Course: Ansible

What Is Configuration Management?

Before starting with Ansible, let’s discuss what configuration management is. Configuration Management (CM) is the process of handling changes in any system systematically, and it maintains the consistency of the product. It retains its consistency because it is applied over the entire lifecycle of the system. Configuration Management provides the capability of controlling and monitoring the performance of the system. Using this capability of monitoring we can prevent errors by notifying and controlling the capability to change anything in the system. If any of node in cluster gets failed we can reconfigure it. Also, configuration management keeps the snapshot of all the version of infrastructure.

Why Configuration Management?

The reason why we should use configuration management is to overcome the difficult situation that we face while setting up the cluster. A few of these are:

  • Managing multiple servers
  • Scaling up and scaling down
  • Syncing up with development team and infrastructure team

What Is Ansible?

Ansible is a radically simple IT automation engine that automates cloud provisioning, configuration management, application deployment, intra-service orchestration, and many other IT needs. It can be used for advanced tasks such as continuous deployments or zero downtime rolling updates. Ansible is a push-based configuration management tool; it means we can push configuration onto the node machine directly without having any central node. It communicates with remote machines over SSH. The main goals of Ansible are ease of use and simplicity.
